This is a pair of new old stock Trico wiper blade refills that are for 13" Trico wiper blades.  These have the bumps in the rubber.  So many of these have been replaced with modern plastic blades that are not even close to what was original in the 50's to 60's.  These fit the following according to my Trico catalog as a replacement refill; 1957-1958 Buick and Cadillac, Oldsmobile and Pontiac; 1958 Chevrolet; 1959 Ford, Edsel, Thunderbird; 1960 Ford Galaxie and Fairlane with vacuum wipers; 1961 Ford with vacuum wipers; 1959-1960 Corvette; Chevrolet light trucks 1959-1965; Ford light trucks 1962-1966; Chevy II 1962-1962 Sport Coupe and Convertible; Chevy II 1963-1966 sport coupe; Valiant and Dart 1965-1966; 1966 Barracuda and Rambler American 1961-1963.   These are in excellent condition.
